The included identification information is stored as reference identification information, and the first measurement result is obtained in descending order of the identification information from the latest first measurement result among the first measurement results accumulated in the first measurement result storage unit. The identification information included in the first measurement result to be transmitted is compared with the reference identification information, and the identification information included in the first measurement result to be transmitted is the reference identification information. When the same as, the first measurement result to be transmitted is transmitted with the power recovery flag which is the power recovery information.
In the measurement date and time calculation unit, the measurement information included in the first measurement result to which the power recovery flag is attached and the first measurement result received thereafter is acquired before the power loss. You may decide that.

A tentative graph arranged in time series according to the difference between the count values at the time of measurement is generated between the measurement information, and the center of the tentative graph in the time direction is the first in which the measurement date and time is invalid. 2 Before and after the measurement result, it may be arranged so as to coincide with the center of the measurement date and time in the time direction, which is not the most recent invalidity.

In this way, even for measurement information for which an accurate measurement date and time cannot be calculated, it is possible to know the relative time-series change with other measurement information for which the measurement date and time is specified.

In addition, in the above measuring equipment,

The loss and recovery of the power supply includes the loss of power when the power plug of the measuring device is pulled out from the outlet and the recovery of power when the power plug of the measuring device is inserted into the outlet. Furthermore, in the case of loss and recovery of power supply, the power supply to the outlet is cut off due to a power failure or the like, so that the power supply of the measuring device in which the power plug is inserted into the outlet is lost and the power supply to the outlet is restarted. This includes the case where the power of the measuring device with the power plug inserted in the outlet is restored.

In addition, the above measuring equipment
The measurement unit may calculate the difference and transmit it to the measurement date / time calculation unit.

In addition, the above measuring equipment
The difference may be calculated by the measurement date and time calculation unit based on the count value at the reference date and time and the count value at the time of measurement transmitted from the measurement unit.

In this way, since the difference is not calculated by the measuring unit, the processing load on the measuring unit can be reduced.

In addition, in the above measuring equipment
The measurement date / time calculation unit determines the power recovery history when the measurement information included in the first measurement result is acquired based on the power recovery history information received from the measurement unit, and determines the power recovery history. At the measurement date and time included in any of the second measurement results having the same power recovery history as, the count value at the time of the measurement corresponding to the second measurement result and the measurement time corresponding to the first measurement result. The measurement date and time of the measurement information corresponding to the first measurement result may be calculated by adding or subtracting the difference from the count value.

In this way, the same power loss is lost to the second measurement result storage unit regardless of the number of the first measurement results that have not been transmitted from the measuring unit to the receiving unit or have been transmitted but not received by the receiving unit. And, if there is a history of recovery and even one second measurement result for which a valid measurement date and time is calculated is accumulated, the measurement date and time can be calculated. Further, since the difference processing of the count value is not performed, the processing load of the measuring unit is small.

In addition, in the above measuring equipment
The measurement date / time calculation unit determines the power recovery history when the measurement information included in the first measurement result is acquired based on the power recovery history information received from the measurement unit, and determines the power recovery history. If a valid measurement date and time has not been calculated for any of the second measurement results having the same power recovery history as, the first measurement result is accumulated in the second measurement result storage unit with the measurement date and time invalidated. You may do so.

In addition, in the above measuring equipment
A display data generation unit for displaying the measurement information in time series is provided.
The display data generation unit attaches the continuous identification information to the measurement information of the second measurement result to which the continuous identification information is attached to the second measurement result in which the measurement date and time is invalid. A tentative graph arranged in time series according to the difference between the count values at the time of measurement is generated between the measurement information, and the center of the tentative graph in the time direction is the first in which the measurement date and time is invalid. 2 Before and after the measurement result, it may be arranged so as to coincide with the center of the measurement date and time in the time direction, which is not the most recent invalidity.

In this way, even for measurement information for which an accurate measurement date and time cannot be calculated, it is possible to know the relative time-series change with other measurement information for which the measurement date and time is specified.

In addition, in the above measuring equipment
The display data generation unit has invalid measurement dates and times for all of the second measurement results of the same power recovery history. When there are a plurality of power recovery histories, the measurement dates and times are invalid for all of the second measurement results. With respect to the power recovery history, the measurement information of the second measurement result to which the continuous identification information is attached is the count value at the time of measurement between the measurement information to which the continuous identification information is attached. A tentative graph arranged in time series according to the difference between the above is generated, and the time direction of the most recent non-invalid measurement date and time before and after the measurement result in which the measurement date and time is invalid is set for a plurality of power recovery histories. Divide into time intervals so that the center of the time interval corresponding to each power recovery history coincides with the center of the provisional graph of the second measurement result in which the measurement date and time for each power recovery history is invalid. It may be arranged in.

In this way, even if there are a plurality of power recovery history information for which the measurement date and time are invalid for all the second measurement results of the same power recovery history information, the measurement date and time can be specified for the measurement information for which an accurate measurement date and time cannot be calculated. It is possible to know the relative time-series change with other measurement information.

According to the present invention, it is possible to provide a measuring device capable of acquiring measurement date and time information without providing a clock.

FIG. 5 is a flowchart showing a flow of a measurement result transmission process from the sphygmomanometer 10 to the smartphone 20.
It is desirable to transmit the measurement result for each measurement so that the smartphone 20 can always keep the latest measurement result. The transmission process of the measurement result may be automatically performed following the measurement of the blood pressure information described with reference to FIG. 4, or may be performed by the user pressing the send button.

First, the control unit 150 establishes communication with the smartphone 20 via the communication unit 130. When the communication between the sphygmomanometer 10 and the smartphone 20 is established, the control unit 150 acquires the current RTC count value at the time of transmission (step S4).

Next, the control unit 150 acquires the latest measurement result, that is, the measurement value having the largest sequence number and the RTC count value at the time of measurement from the measurement result recording unit 180 (step S5).

Next, the control unit 150 calculates the difference between the current RTC count value at the time of transmission acquired in step S4 and the RTC count value at the time of measurement acquired in step S5 (step S6).

Then, the control unit 150 transmits the latest measurement result including the difference between the measurement having the largest sequence number acquired in step S5 and the RTC count value calculated in step S6 to the smartphone 20 via the communication unit 130. (Step S7).

Next, the control unit 150 acquires the past measurement results, that is, the measurement value of the second highest sequence number and the RTC count value at the time of measurement from the measurement result recording unit 180 (step S8).

Next, the control unit 150 calculates the difference between the current RTC count value at the time of transmission acquired in step S4 and the RTC count value at the time of measurement acquired in step S8 (step S9).

Then, the control unit 150 transmits the past measurement results including the difference between the measurement value of the second largest sequence number acquired in step S8 and the RTC count value calculated in step S9 via the communication unit 130. It is transmitted to 20 (step S10). Here, the measurement results for the past may be acquired one by one and transmitted, or a plurality of measurement results may be collectively acquired and transmitted. Further, the acquisition and transmission of one or a plurality of measurement results may be repeated to transmit all the measurement results stored in the measurement result recording unit 180 to the smartphone 20.

As described above, as a normal process, if the latest measurement result and the past measurement result are transmitted from the sphygmomanometer 10 to the smartphone 20 for each measurement of the blood pressure information, the battery is temporarily replaced. Even if, in the smartphone 20, for the latest measurement result after battery replacement, the difference between the RTC count value at the time of transmission and the RTC count value of the measured value is subtracted from the date and time information at the time of transmission. , The measurement date and time can be calculated.

However, when only one-way communication from the sphygmomanometer 10 to the smartphone 20 is performed, the sphygmomanometer 10 cannot recognize the transmission from the sphygmomanometer 10 even if it is not received by the smartphone 20. Further, due to some inconvenience of the sphygmomanometer 10, the latest measurement result or the past measurement result may not be transmitted.
Even in such an exceptional case, the process described later enables the smartphone 20 to specify the measurement date and time for the measurement result measured by the sphygmomanometer 10 having no clock function.

[Process flow from measurement of blood pressure information on a sphygmomanometer to processing of transmission of measurement results to a smartphone]
FIG. 6 is a flowchart showing an example of a processing flow from the measurement of blood pressure information to the processing of transmitting the measurement result to the smartphone 20 in the sphygmomanometer 10.

When the user measures the blood pressure information with the sphygmomanometer 10, the control unit 150 performs the measurement process and the measurement result recording process shown in FIG. 4 (step S11).

Next, the control unit 150 of the sphygmomanometer 10 performs the measurement result transmission process shown in FIG. 5 at a predetermined timing (step S12).

When the user first turns on the power after replacing the battery of the sphygmomanometer 10, the control unit 150 performs a predetermined power-on processing (step S13).
Here, the latest sequence among the sequence numbers assigned to each of the measurement results recorded in the predetermined area (hereinafter, also referred to as “measurement result memory”) of the measurement result recording unit 180 composed of the non-volatile memory. The number is stored in a predetermined area of the measurement result recording unit 180 as the sequence number before power exchange. The area in which the sequence number before power exchange is stored is not limited to the measurement result recording unit 180, and may be stored in another area of the non-volatile memory included in the storage unit 170. When the power is turned on, the control unit 150 performs various other initialization processes, but these are well-known processes and will not be described in detail. In the present embodiment, the sequence number corresponds to the identification information, and the sequence number before battery replacement corresponds to the battery replacement information and the reference identification information.

In this way, if only the sequence number before power replacement is stored, the processing load at the time of the first power-on after battery replacement can be reduced, and the time required for processing can also be shortened.

When the user turns on the power after replacing the battery and measures the blood pressure information, the control unit 150 performs the measurement process and the measurement result recording process shown in FIG. 4 (step S14).

Next, the control unit 150 performs a measurement result transmission process described later from the sphygmomanometer 10 to the smartphone 20 at a predetermined timing (step S15). The timing at which the sphygmomanometer 10 transmits the measurement result to the smartphone 20 may be such that the measurement result including the past portion is transmitted every time the blood pressure information is measured, or the user presses the send button included in the input unit 140. It may be the timing when is pressed, or it may be the timing when the control unit 150 determines that the power is turned on, the elapse of a predetermined time, the measurement has been performed a predetermined number of times, and the like, and can be appropriately set.

As the power-on processing after battery replacement described above, even if the battery replacement flag indicating whether or not the battery is replaced is set to 1 for all the measurement results recorded in the measurement result memory at the time of power-on. Good. In this way, when transmitting the measurement result, the processing load at the time of transmission is reduced and the time required for processing can be reduced as compared with the case where the battery replacement flag is set based on the sequence number before battery replacement.
Further, as the power-on processing after the battery replacement described above, the battery is replaced only for the latest measurement result among the measurement results stored in the measurement result memory at the time of power-on, that is, the measurement result with the latest sequence number. The flag may be set to 1. In this way, the processing load can be reduced and the time required for processing can be shortened as compared with setting the battery replacement flag to 1 for all the measurement results.

FIG. 6 illustrates, and is not limited to, the flow of processing from the measurement of blood pressure information to the processing of transmitting the measurement result to the smartphone 20 in the sphygmomanometer 10. The measurement process and the measurement result recording process shown in steps S11 and S14 of FIG. 6 are generally repeated a plurality of times. Further, in FIG. 6, the battery replacement is performed once before the measurement result is transmitted, but it may be performed a plurality of times. Blood pressure information may be measured one or more times during multiple battery changes. In addition, the measurement result may be transmitted without measuring the blood pressure information after the power-on processing is performed after the battery is replaced.

[Sending measurement results from blood pressure monitor to smartphone]
FIG. 7 is a flowchart showing a procedure for transmitting data including measurement results from the sphygmomanometer 10 to the smartphone 20.
First, the control unit 150 establishes communication with the smartphone 20 via the communication unit 130. When the communication between the sphygmomanometer 10 and the smartphone 20 is established, the control unit 150 acquires the current RTC count value at the time of transmission (step S21). In the present embodiment, the current time point at the time of transmission when the communication between the sphygmomanometer 10 and the smartphone 20 is established corresponds to the reference date and time.

Next, the control unit 150 acquires the pre-battery replacement sequence number from the predetermined area of the non-volatile memory (step S22).
Here, the data configuration of the measurement result recording unit 180 will be described with reference to FIGS. 8A and 8B. 8A and 8B are diagrams schematically showing the structure of the data recorded in the measurement result recording unit 180. Here, the measurement results (not shown) are associated with sequence numbers assigned in ascending order (stored in the column of the title row “#” in FIG. 8A). Then, in the measurement result recording unit 180, the RTC count value at the time of measurement (stored in the column of the title row “RTC” in FIG. 8A) is associated with each measurement result. As shown in FIG. 8A, the count value at the time of measurement of the measurement result with the sequence number 1 is 4722237 seconds (hereinafter, the unit is omitted and only the numerical value is shown for the count value). The larger the sequence number is, the later the measurement result is measured, so that the RTC count value, which is the elapsed time from the power ON, is also large. However, when the battery is replaced, the RTC count value is cleared and returns to 0. As described above, in the sphygmomanometer 10, when the power is turned on after the battery replacement, the latest (maximum) sequence number at that time is stored as the sequence number before the battery replacement. In FIG. 8A, since the batteries are exchanged between the measurements of the sequence numbers 27 and 28, the sequence number 27 is stored as the sequence number before the battery exchange.
Explaining with reference to FIG. 8A, in step S22, “27” is acquired as the sequence number before battery replacement.

Next, the control unit 150 acquires the measurement result and the RTC count value at the time of measurement from the measurement result recording unit 180 in the order of newest measurement results (step S23), that is, in descending order from the one with the largest sequence number (step S24). ).

Then, the control unit 150 determines whether or not the sequence number of the measurement result acquired in step S23 is equal to or less than the sequence number before battery replacement acquired in step S22 (step S25).

When No is determined in step S25, that is, when the sequence number of the measurement result acquired in step S24 is larger than the sequence number before battery replacement acquired in step S22, the control unit 150 measures after battery replacement. Since this is the result, the battery replacement flag is set to 0 (step S26). In the example shown in FIG. 8B, since the measurement results of sequence numbers 28 to 30 are after battery replacement, 0 indicating OFF is set in the battery replacement flag. Then, the control unit 150 sets the difference time as the difference time obtained by subtracting the RTC count value at the time of measurement of the measurement result acquired in step S24 from the current RTC count value acquired in step S21 (step S27). In the example shown in FIG. 8B, the measurement result of sequence number 30 is 0, which is obtained by subtracting 2880, which is the RTC count value at the time of measurement, from the current RTC count value 2880 according to the difference calculation formula in step S27. Is set as the difference time. Similarly, for the measurement result of sequence number 29, 1440, which is a value obtained by subtracting 1440 from 2880, is set as the difference time. Similarly, for the measurement result of sequence number 28, 2820, which is a value obtained by subtracting 60 from 2880, is set as the difference time. Then, the control unit 150 transmits the blood pressure information, the sequence number, the value of the battery replacement flag set in step S16, and the difference time set in step S27 as the measurement result for one case via the communication unit 130. The value of is transmitted to the smartphone 20 (step S28).

When it is determined Yes in step S25, that is, when the sequence number of the measurement result acquired in step S24 is equal to or less than the sequence number before battery replacement acquired in step S22, the control unit 150 measures before battery replacement. Since this is the result, the battery replacement flag is set to 1 (step S29). In the example shown in FIG. 8B, since the measurement results of sequence numbers 1 to 27 are before battery replacement, 1 indicating ON is set in the battery replacement flag. The measurement results having the sequence number 24 or less have already been transmitted to the smartphone 20, and as shown in FIG. 11, the measurement date and time are specified for these measurement results on the smartphone 20. Then, the control unit 150 determines whether or not the measurement result is the oldest history (step S20). Here, whether or not the history is the oldest is determined by whether or not the measurement result of the smaller sequence number is stored in the measurement result recording unit 180.

If it is determined to be Yes in step S30, the control unit 150 sets “invalid” as the difference time (step S31), and proceeds to step S28. In the example shown in FIG. 8A, since the measurement result of sequence number 1 is the oldest history, "invalid" is set as the difference time.

If No is determined in step S30, the control unit 150 acquires the RTC count value at the time of the previous measurement from the measurement result recording unit 180 (step S32).

Then, the control unit 150 determines whether or not the RTC count value at the time of the previous measurement acquired in step S32 is equal to or less than the RTC count value acquired in step S24 (step S33).

If No is determined in step S33, the control unit 150 sets “invalid” as the difference time (step S34), and proceeds to step S28. Normally, the RTC count value at the time of the previous measurement acquired in step S32 does not exceed the RTC count value acquired in step S24. Therefore, in such a case, one of the measurement results is incorrect. Since it is considered that there is, set "invalid" as the difference time.

If it is determined to be Yes in step S33, the control unit 150 counts the RTC at the time of the previous measurement acquired in step S22 from the RTC count value at the time of measurement acquired in step S24 as the difference time. A value obtained by subtracting the value is set (step S15), and the process proceeds to step S28. In the example shown in FIG. 8B, the RTC at the time of the previous measurement is obtained from the RTC count value of 4768317 of the measurement result of the sequence number 27 according to the difference calculation formula of step S35 with respect to the measurement result of the sequence number 27. The difference time is set to 1440, which is the RTC count value of the measurement result of sequence number 27 minus 47668777. Similarly, 1440 is set as the difference time for the measurement result of the sequence number 26. Similarly, 1440 is set as the difference time for the measurement result of the sequence number 25.

When the processes from step S24 to step S28 are repeated in order from the new measurement result for all the measurement results (step S36), the control unit 150 disconnects the communication with the smartphone 20 via the communication unit 130 and ends. ..

[Measurement date / time identification processing on a smartphone that receives measurement results from a blood pressure monitor]
FIG. 9 is a flowchart showing a procedure of processing for receiving data including measurement results from the sphygmomanometer 10 on the smartphone 20.

When the communication with the sphygmomanometer 10 is established and the communication is started, the control unit 240 acquires the current date and time information from the clock unit 250 (step S41).

Next, the control unit 240 receives the measurement results one by one via the communication unit 210 until the communication with the sphygmomanometer 10 is completed (step S42). At this time, since the measurement results are transmitted from the sphygmomanometer 10 in order from the one having the largest sequence number, the smartphone 20 receives the measurement results in order from the one having the largest sequence number.
The control unit 240 determines whether or not the measurement result of the sequence number (Sq) of the received measurement result is stored in the measurement result recording unit 260 and a valid measurement date and time is specified for the measurement result ( Step S44).

If No is determined in step S44, the measurement result is stored in the measurement result recording unit 260 (step S45), and the process proceeds to step S47.
If Yes is determined in step S44, the measurement result is discarded without being saved (step S46), and the process proceeds to step S47.

In step S47, it is determined whether or not the sequence number Sq of the measurement result received in step S43 is Sqmax-N + 1. Here, Sqmax has the largest sequence number among the measurement results received from the sphygmomanometer 10. N is the number of cases that can be recorded in the measurement result memory of the measurement result recording unit 180 of the sphygmomanometer 10. Since Sqmax is transmitted from the sphygmomanometer 10 in descending order from the sequence number having the highest measurement result, the sequence number of the measurement result received first may be stored in a predetermined area of the measurement result recording unit 260. Alternatively, it may be transmitted from the sphygmomanometer 10 separately from the measurement result. Further, the value of N may be transmitted from the sphygmomanometer 10 to the smartphone 20 and stored in a predetermined area of the storage unit 230 when the sphygmomanometer 10 and the smartphone 20 can be recognized by pairing or the like. However, the method of acquiring the value of N is not limited to this.

If Yes is determined in step S47, the communication is terminated.
If No is determined in step S47, the process returns to step S43 to receive the next measurement result.

FIG. 10 is a flowchart showing a procedure of a process for specifying a measurement date and time executed by the smartphone 20 with respect to the measurement result received according to FIG. The measurement date / time specifying process in the control unit 240 will be described below with reference to FIG.

The control unit 240 repeats the processing of the measurement results received in steps S43 to S46 in ascending order of sequence number (step S51).

First, the control unit 240 acquires one of the measurement results received in steps S43 to S46 from the measurement result recording unit 260, which has the smallest sequence number (step S52).
The control unit 240 determines whether or not the data set as the difference time is "invalid" in the measurement result acquired in step S52 (step S53).

If it is determined to be Yes in step S53, the control unit 240 sets “invalid” as the measurement date and time (step S54). Then, the control unit 240 records the measurement result and the measurement date and time in the measurement result recording unit 260 (step S55).

If No is determined in step S53, the control unit 240 determines whether or not the battery has been replaced (step S56). Here, the control unit 240 determines whether or not the battery has been replaced based on the value of the battery replacement flag included in the measurement result received from the sphygmomanometer 10.

When the battery is not replaced in step S56, that is, when the battery replacement flag is determined to be 0, the control unit 240 is included in the measurement result received in step S44 from the current date and time acquired in step S41 as the measurement date and time. A value obtained by subtracting the value of the difference time is set (step S57). Then, the process proceeds to step S55. FIG. 11 is a diagram schematically showing the structure of data recorded in the measurement result recording unit 260, corresponding to the examples shown in FIGS. 8A and 8B. In the example shown in FIG. 11, the battery replacement flag of the measurement results of sequence numbers 28 to 30 is set to 0. Therefore, the measurement result of the sequence number 30 is a value obtained by subtracting 0 seconds set as the difference time from the current date and time of 10:00 on July 5, according to the date and time calculation formula in step S57. 10:00: 00 on July 5 is set as the measurement date and time. Similarly, for the measurement result of sequence number 29, 9:37:00 on July 5, which is a value obtained by subtracting 1440 seconds from 10:00 on July 5, is set as the measurement date and time. Similarly, for the measurement result of sequence number 28, the measurement date and time is set to 9:13:00 on July 5, which is a value obtained by subtracting 2820 seconds from 10:00 on July 5.

When the battery is replaced in step S56, that is, when the battery replacement flag is determined to be 1, the control unit 240 has the measurement result of the measurement date and time immediately before the measurement result recording unit 260, that is, the sequence number is 1. Obtain the smallest measurement result (step S58).

Then, the control unit 240 determines whether or not a valid value is set as the measurement date and time of the measurement result acquired in step S58 (step S59).

If No is determined in step S59, that is, if "invalid" is set as the measurement date and time included in the measurement result of the previous measurement date and time, the measurement date and time of the measurement result acquired in step S52 is also set. Set as "invalid" (step S60). Then, the process proceeds to step S55.

If it is determined to be Yes in step S59, that is, if a valid value is set as the measurement date and time included in the measurement result of the previous measurement date and time, the previous measurement date and time acquired in step S58 is set. A value obtained by adding the difference time included in the measurement result acquired in step S52 is set as the measurement date and time (step S61). Then, the process proceeds to step 55. In the example shown in FIG. 11, the battery replacement flag included in the measurement result of sequence number 25 is 1, and the previous measurement date and time is 10:24:00 on July 3 of sequence number 24. Therefore, 10:48:00 on July 3, which is the value obtained by adding 1440 seconds, which is the difference time included in the measurement result of sequence number 25, to 10:24:00 on July 3, is set as the measurement date and time. To. Similarly, for the measurement result of sequence number 26, the measurement date and time is set to 11:12:00 on July 3, which is the value obtained by adding 1440 seconds to 10:48:00 on July 3. Similarly, for the measurement result of sequence number 27, the measurement date and time is set to 11:26:00 on July 3, which is the value obtained by adding 1440 seconds to 11:12:00 on July 3.

The control unit 240 repeats the processes of steps S52 to S55 until the measurement results received in steps S43 to S46 have the largest sequence number (step S62).

As described above, according to the health information management system 1 according to the present embodiment, the measurement date and time information can be acquired by the smartphone 20 without providing the blood pressure monitor 10 with a clock.

[Exceptional case where the measurement date and time cannot be specified]
By the above-mentioned processing, it is possible to specify the measurement date and time of the blood pressure information performed by the sphygmomanometer 10 without a clock on the smartphone 20, but in the cases described below, the sphygmomanometer 10 is exceptionally provided on the smartphone 20. It is not possible to specify the measurement date and time of blood pressure information.

[Case 1]
The measurement result is not transmitted from the sphygmomanometer 10 to the smartphone 20 for some reason, or the measurement result transmitted from the sphygmomanometer 10 is not received by the smartphone 20 for some reason. In such a case, since the reference measurement date and time is not held in the smartphone 20, the measurement date and time cannot be specified.

[Case 2]
An exceptional case 2 will be described with reference to FIGS. 12A, 12B and 13. 12A and 12B are diagrams schematically showing the structure of the data recorded in the measurement result recording unit 180 of the sphygmomanometer 10. Further, FIG. 13 is a diagram schematically showing the data structure of the measurement result recording unit 260 of the smartphone 20.
Here, the number N that can be recorded in the measurement result recording unit 180 of the sphygmomanometer 10 is finite, and when N or more are measured, the oldest measurement results are deleted in order. Then, after the last time the smartphone 20 receives the measurement result, the measurement is performed N times or more, and the battery is replaced while the measurement is performed within N times from the latest, the blood pressure monitor 10 to the smartphone 20 Case 2 corresponds to the case where the measurement result is transmitted to.

In the example shown in FIG. 12A, N = 30, 5 cases of sequence numbers 1 to 5 are erased, and sequence numbers 6 to 35 are recorded. The measurement results of sequence numbers 1 to 5 have already been transmitted from the sphygmomanometer 10 to the smartphone 20, and as shown in FIG. 12, the measurement results of sequence number 5 are sent to the measurement results of sequence number 5 at 16:42 on June 16. The measurement date and time are specified as: 00. In the sphygmomanometer 10, since the measurement results before the sequence number 5 are deleted, the difference time cannot be calculated according to the difference calculation formula for the measurement result of the sequence number 6, and the difference time setting is "invalid". Will be. Therefore, in the smartphone 20, since there is no reference measurement date and time for the measurement results of the sequence numbers 6 to 32, the measurement date and time cannot be specified, and any measurement date and time is set as "invalid".

In the above process, for the measurement result set as "invalid" as the measurement date and time, that is, for the measurement results of sequence numbers 6 to 32 in the example shown in FIG. 13, the measurement result is the difference time data received from the sphygmomanometer 10. It may be stored in the recording unit 260. In this way, even for the data set as "invalid" as the measurement date and time, the interval between the measurement dates and times can be specified, so that the relative time change of the blood pressure information can be displayed on the touch panel display 220.

FIG. 14 shows a display example of the time course of systolic blood pressure as blood pressure information.
Here, it is assumed that the measurement dates and times such as t _n and t _m are specified for the measurement results of the sequence number n or less and the sequence number m or more, respectively. On the other hand, the measurement date and time are set to "invalid" for all the measurement results of the sequence numbers k to k + 3. At this time, regarding the measurement results of the sequence numbers k to k + 3, the intervals of the measurement dates and times of the sequence numbers k to k + 1, the sequence numbers k + 1 to k + 2, and the sequence numbers _{k + 2 to k + 3} are the RTC counts T _k , T _{k + 1} , and T _{k + 2.} It can be specified by the value. Therefore, the time interval of the data corresponding to these sequence numbers is set corresponding to the interval of the count value of each RTC. Then, when a provisional graph of the measurement result whose measurement date and time is "invalid" is placed in the graph showing the time-series change of the measurement result, the measurement result whose measurement date and time is "invalid" is arranged. The center in the time direction can be arranged so as to coincide with the median value between the effective measurement dates and times before and after that. A tentative graph of the measurement results of the data of sequence numbers k to k + 3 shows the measurement results in which the center of the measurement time interval is older than the measurement result in which the measurement date and time is "invalid" and the measurement date and time is specified. The latest one (sequence number n) and the oldest measurement result (sequence number m) that is newer than the measurement result in which the measurement date and time is "invalid" and whose measurement date and time is specified, respectively. median measurement date and time, here, arranged in time series graph of the measurement results of the systolic blood pressure to match the _{(t m + t n) /} 2.
In this way, even for measurement results for which the exact measurement date and time cannot be specified, it is possible to know the relative time-series changes with other measurement results for which the measurement date and time can be specified, which is useful information for health management. Can be provided.
In the example shown in FIG. 14, the case where the sequence number n and the sequence number k and the sequence number k + 3 and the sequence number m are not necessarily continuous has been described, but each may be continuous.

[Case 3]
An exceptional case 3 will be described with reference to FIGS. 15A, 15B and 16. 15A and 15B are diagrams schematically showing the structure of data recorded in the measurement result recording unit 180 of the sphygmomanometer 10. Further, FIG. 16 is a diagram schematically showing the data structure of the measurement result recording unit 260 of the smartphone 20.
Case 3 is a case where the battery is replaced twice or more after the sphygmomanometer 10 finally transmits the measurement result to the smartphone 20. In such a case, the measurement date and time can be specified for the measurement result until the first battery replacement, but the measurement date and time cannot be specified for the measurement result after the second battery replacement and before the latest battery replacement.

In the example shown in FIG. 15A, the battery is replaced twice, between the sequence number 23 and the sequence number 24, and between the sequence number 27 and the sequence number 28. For sequence numbers 21 to 23, sequence numbers 25 to 27, and sequence numbers 28 to 30, the difference time can be calculated according to the difference calculation formula described in the first embodiment, but the difference calculation is performed for the measurement result of sequence number 24. Is not possible, so "invalid" is set as the difference time. At this time, since the measurement results of the sequence numbers 1 to 20 have already been transmitted from the sphygmomanometer 10 to the smartphone 20, the specified measurement date and time is sent to the measurement result recording unit 260 as shown in FIG. It has been recorded.
Therefore, with respect to the measurement results of sequence numbers 21 to 23 and sequence numbers 28 to 30, the measurement date and time can be specified according to the date and time calculation formula described in Example 1. However, since there is no reference measurement date and time for the measurement results of sequence numbers 24 to 27, the measurement date and time cannot be specified, and any measurement date and time is set as "invalid".

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described. The hardware configuration of the health information management system 1 according to the present embodiment is the same as that of the first embodiment. Further, the overall flow of the process from the measurement of the blood pressure information by the sphygmomanometer 10 and the process from the measurement of the blood pressure information by the sphygmomanometer to the process of transmitting the measurement result to the smartphone 20 is the same as in the first embodiment. For the same processing as in the first embodiment, the same reference numerals are used and detailed description thereof will be omitted.

In the present embodiment, the details of the measurement result transmission from the sphygmomanometer 10 to the smartphone 20 and the measurement date / time identification process in the smartphone 20 receiving the measurement result from the sphygmomanometer 10 are different from those in the first embodiment.

FIG. 17 is a flowchart showing a procedure for transmitting data including measurement results from the sphygmomanometer 10 according to the second embodiment to the smartphone 20. The same reference numerals are given to the processes common to those in the first embodiment, and detailed description thereof will be omitted.

In the present embodiment, instead of assigning a battery replacement flag to all the measurement results stored in the measurement result memory and transmitting the measurement results to the smartphone 20, the measurement results are given the same sequence number as the sequence number before the battery replacement. Only the battery replacement flag 1 is added and transmitted.

As shown in FIG. 17, when the measurement result is acquired from the measurement result recording unit 180, the control unit 150 compares the sequence number (Sq) of the measurement result with the pre-battery replacement sequence number (Sqc) acquired in step S22. (Step S71).

If it is determined in step S71 that Sq> Sqc, that is, the sequence number of the measurement result is larger than the sequence number before battery replacement, the measurement result is after battery replacement, and the process proceeds to step S27.

In step S71, when it is determined that Sq = Sqc, that is, the sequence number of the measurement result is the same as the sequence number before battery replacement, the battery replacement flag 1 is added (step S72), and the process proceeds to step S30.

If it is determined in step S71 that Sq <Sqc, that is, the sequence number of the measurement result is smaller than the sequence number before battery replacement, the measurement result is before battery replacement, and the process proceeds to step S30.

Next, the control unit 150 acquires the pre-battery replacement sequence number from the predetermined area of the measurement result recording unit 180 (step S83).

Next, the control unit 150 acquires the blood pressure information as the measurement result and the RTC count value at the time of measurement from the measurement result recording unit 180 in the order of newest measurement results (step S84), that is, in descending order from the one having the largest sequence number. (Step S85).

Then, the control unit 150 determines whether or not the sequence number of the measurement result acquired in step S85 is equal to or less than the sequence number before battery replacement acquired in step S63 (step S86).

When No is determined in step S86, that is, when the sequence number of the measurement result acquired in step S85 is larger than the sequence number before battery replacement acquired in step S83, the control unit 150 measures after battery replacement. Since this is the result, the battery replacement flag is set to 0 (step S87).

Then, the control unit 150 transmits the blood pressure information, the RTC count value at the time of measurement, and the battery replacement flag to the smartphone 20 as the measurement result for one case via the communication unit 130 (step S88).

When it is determined Yes in step S86, that is, when the sequence number of the measurement result acquired in step S85 is equal to or less than the sequence number before battery replacement acquired in step S83, the control unit 150 measures before battery replacement.

The same reference numerals are given to the processes common to those in the first embodiment, and detailed description thereof will be omitted.

When the communication with the sphygmomanometer 10 is established and the communication is started, the control unit 240 acquires the current date and time information from the clock unit 250 (step S41).

Next, the control unit 240 receives the RTC count value at the time of transmission from the sphygmomanometer 10 via the communication unit 210 (step S78). The received RTC count value at the time of transmission is stored in a predetermined area of the non-volatile memory included in the storage unit 230.

Next, the control unit 240 determines whether the value of the battery replacement flag included in the measurement result acquired in step S92 is 0 or 1 (step S93).

The case where the value of the battery replacement flag is determined to be 0 in step S93 is the case where the measurement result acquired in step S92 is after the battery replacement. In this case, the control unit 240 sets the difference time as the difference time obtained by subtracting the RTC count value at the time of measurement of the measurement result acquired in step S92 from the RTC count value at the time of transmission received in step S77 ( Step S94).

Next, the control unit 240 sets the measurement date and time as a value obtained by subtracting the value of the difference time calculated in step S94 from the current date and time acquired in step S41 (step S95). Then, the measurement date and time set in this way are recorded in the measurement result recording unit 260 (step S9).
6).

When the value of the battery replacement flag is determined to be 1 in step S93, that is, when the measurement result acquired in step S92 is the one before battery replacement, the control unit 240 has the oldest history of the measurement result. It is determined whether or not it is (step S97). Here, whether or not the history is the oldest is determined by whether or not the measurement result of the smaller sequence number is received.

If it is determined to be Yes in step S97, the control unit 240 sets the difference time as "invalid" (step S98) and sets the measurement date and time as "invalid" (step S99). Then, the process proceeds to step S96.

If No is determined in step S97, the control unit 240 acquires the RTC count value at the time of the previous measurement (step S100).

Then, the control unit 240 determines whether or not the RTC count value at the time of the previous measurement acquired in step S100 is equal to or less than the RTC count value received in step S72 (step 101).

If No is determined in step S101, the control unit 240 sets the difference time as "invalid" (step S102) and sets the measurement date and time as "invalid" (step S103). Then, the process proceeds to step S96.

If it is determined to be Yes in step S101, the control unit 240 counts the RTC at the time of the previous measurement acquired in step S100 from the RTC count value at the time of measurement received in step S72 as the difference time. A value obtained by subtracting the value is set (step S104). Then, the previous measurement date and time is acquired (step S105).

Next, the control unit 240 determines whether or not a valid value is set as the measurement date and time of the measurement result acquired in step S105 (step S106).

When No is determined in step S106, that is, when "invalid" is set as the measurement date and time included in the measurement result of the previous measurement date and time, the measurement date and time of the measurement result acquired in step S92 is also set. It is set to "invalid" (step S107). Then, the process proceeds to step S96.

When it is determined Yes in step S106, that is, when a valid value is set as the measurement date and time included in the measurement result of the previous measurement date, the previous measurement date and time acquired in step S87 is set. A value obtained by adding the difference time calculated in step S104 is set as the measurement date and time (step S108). Then, the process proceeds to step S96.

The control unit 240 repeats the processes of steps S93 to S96 until the measurement results received in steps S43 to S46 have the largest sequence number (step S109).

As described above, according to the health information management system 1 according to the present embodiment, the measurement date and time information can be acquired by the smartphone 20 without providing the blood pressure monitor 10 with a clock.
Further, when the measurement result is transmitted from the sphygmomanometer 10 to the smartphone 20 in this way, the RTC count value at the time of measurement is transmitted to the smartphone 20 as it is without calculating the difference time on the sphygmomanometer 10 side, and the smartphone 20 By calculating the difference time required on the side
The processing load at the time of transmission of the sphygmomanometer 10 can be reduced, and the time required for processing can be shortened.

[Send measurement results to smartphone]
FIG. 26 is a flowchart showing a flow of a measurement result transmission process from the sphygmomanometer 10 to the smartphone 20 according to the present embodiment.
After establishing communication with the smartphone 20, the control unit 150 acquires the current RTC count value at the time of transmission (step S81) and transmits the RTC to the smartphone 20 via the communication unit 130 (step S82). In the present embodiment, the control unit 150 next acquires the latest battery replacement count information from the predetermined area of the storage unit 170 (step S112) and transmits it to the smartphone 20 via the communication unit 130 (step S113).

When the processes of steps S115 and S116 are repeated in descending order from the new measurement results for all the measurement results (step S117), the control unit 150 disconnects the communication with the smartphone 20 via the communication unit 130 and ends. ..

[Measurement date / time identification processing on a smartphone that receives measurement results from a blood pressure monitor]
FIG. 27 is a flowchart showing a procedure of processing for receiving data including measurement results from the sphygmomanometer 10 on the smartphone 20.

When the communication with the sphygmomanometer 10 is established and the communication is started, the control unit 240 acquires the current date and time information from the clock unit 250 (step S41).

Next, the control unit 240 receives the RTC count value at the time of transmission from the sphygmomanometer 10 via the communication unit 210 (step S77). The received RTC count value at the time of transmission is stored in a predetermined area of the non-volatile memory included in the storage unit 230.
Then, the control unit 240 receives the latest battery replacement frequency information from the sphygmomanometer 10 via the communication unit 210 (step S118). The latest battery replacement frequency information received is stored in a predetermined area of the non-volatile memory included in the storage unit 230.
The processing after step S42 is the same as that of the first embodiment shown in FIG.

FIG. 28 is a flowchart showing a procedure of processing for specifying the measurement date and time executed by the smartphone 20 with respect to the measurement result received according to FIG. 27. FIG. 29A is a diagram showing an example of the data structure of the measurement result recording unit 180 in the sphygmomanometer 10 according to the present embodiment. FIG. 29B is a diagram showing a specific example of the measurement date / time specifying process and a part of the data structure in the smartphone 20 according to the present embodiment. The measurement date / time specifying process in the control unit 240 will be described below with reference to FIG. 28. In the example shown in FIG. 29A, the number of cases that can be recorded in the measurement result recording unit 180 of the sphygmomanometer 10 is 30. In this example, the first battery replacement is performed between the measurement of sequence number 23 and the measurement of sequence number 24, and the second battery replacement is performed between the measurement of sequence number 27 and the measurement of sequence number 28. It is done. Therefore, 0 is recorded as the battery replacement count information for the sequence numbers 1 to 23, 1 is recorded as the battery replacement count information for the sequence numbers 24 to 27, and 2 is recorded as the battery replacement count information for the sequence numbers 28 to 30. It has been recorded. Here, the latest battery replacement count is 2. Further, in FIG. 29B, in addition to the blood pressure information, the battery replacement frequency information and the RTC count value of the measurement result are also recorded. In the example shown in FIG. 29B, the measurement results of the sequence number 1 and the sequence number 25 at the time of measurement are appropriately transmitted to the smartphone 20 to specify an effective measurement date and time.

The control unit 240 acquires the latest battery replacement frequency information stored in a predetermined area of the storage unit 230 (step S116). In the example of FIG. 29A, "2" is acquired.
Next, the control unit 240 repeats the processing of the measurement results received in steps S43 to S46 in ascending order of sequence number (step S117).

First, the control unit acquires measurement results one by one from the measurement result recording unit 260 (step S118).
Then, the control unit 240 determines whether or not the battery replacement number information (Ch) included in the measurement result acquired in step S118 is equal to the latest battery replacement number information (Chp) received in step S116 (step S119). ). Here, as described above, Chp = 2.

The case where Ch = Chp is determined in step S119 is a case where the battery has not been replaced yet after the measurement result acquired in step S118 is measured. In this case, the control unit 240 sets the difference time as the difference time obtained by subtracting the RTC count value at the time of measurement of the measurement result acquired in step S118 from the RTC count value at the time of transmission received in step S77 ( Step S120). In the example of FIG. 29A, for the measurement results of sequence numbers 28 to 30, the difference time obtained by subtracting the RTC count values of 2880, 1440, and 60 at the time of measuring each measurement result from the RTC count value of 2880 at the time of transmission. 0,1440,2820 is obtained.
Next, the control unit 240 sets the measurement date and time as a value obtained by subtracting the value of the difference time calculated in step S121 from the current date and time acquired in step 41 (step S121). Then, the measurement date and time set in this way are recorded in the measurement result recording unit 260 (step S122). In the example of FIG. 29A, the measurement date and time of the measurement results of sequence numbers 30 to 28 is July 5th by subtracting the difference time 0.1440, 2820 from the current date and time of 10:00 on July 5th. It is specified as 10:00:00, 9:37:00, and 2:13: 00.

The case where it is determined in step S119 that Ch = Chp is not the case, that is, the case where the battery is replaced at least once after the measurement result acquired in step S118 is measured. In this case, the control unit 240 searches for the measurement result having the same battery replacement frequency information as the measurement result acquired in step S118 among the measurement results recorded in the measurement result recording unit 260 (step S123), and the same. It is determined whether or not there is a measurement result having the battery replacement count information and recording a valid measurement date and time (step S124). In the example of FIG. 29B, since the number of battery replacements is not 2 for the measurement results of sequence numbers 1 to 27, the measurement results recorded in the measurement result recording unit 260 are searched. Then, it is determined that the measurement result of the battery replacement number of 0 times includes the measurement result of sequence number 1 as the measurement result in which the effective measurement date and time is specified, and the measurement result of the battery replacement number of 1 time is valid. It is determined that there is a measurement result of sequence number 25 as a measurement result for which the measurement date and time is specified.

If No is determined in step S124, the measurement date and time cannot be specified for the measurement result acquired in step S118. Therefore, “invalid” is set as the measurement date and time (step S125), and the process proceeds to step S122.

If it is determined to be Yes in step S124, the control unit 240 has the same battery replacement count information as the measurement result acquired in step S118 among the measurement results recorded in the measurement result recording unit 260, and The measurement result in which the effective measurement date and time is recorded is acquired as reference data (step S126). When there are a plurality of measurement results that can be used as reference data, for example, the measurement result having the smallest sequence number is selected, but any one of them may be selected for the processing described later, so the selection condition is this. Not limited to. In the example of FIG. 29B, the measurement result of sequence number 1 is acquired as reference data from the measurement result of 0 times of battery replacement, and the measurement result of sequence number 25 is acquired as reference data from the measurement result of 1 time of battery replacement. Will be done.

Next, the control unit 240 determines whether or not the RTC count value at the time of measuring the reference data is equal to or less than the RTC count value at the time of measuring the measurement result acquired in step S118 (step S127).

When it was determined to be Yes in step S127, the control unit 240 subtracted the RTC count value at the time of measuring the reference data from the RTC count value at the time of measuring the measurement result acquired in step S118 as the difference time. Set the value (step S128). Then, the control unit 240 acquires the measurement date and time of the reference data (step S129), and adds the difference time set in step S128 to the measurement date and time acquired in step S129 as the measurement date and time of the measurement result acquired in step S118. The value is set (step S130). Then, the process proceeds to step S122. In the example of FIG. 29B, for the measurement results of sequence numbers 20 to 23 and sequence numbers 26 and 27, the RTC count value of the reference data is equal to or less than the RTC count value at the time of each measurement. Therefore, 41660, 43200, 44640, 46080 can be obtained as the difference time by subtracting the count value 4722237 of the reference data from the RTC count value at the time of measuring the measurement results of the sequence numbers 20 to 23. Then, by adding these difference times to the measurement date and time of the reference data, which is 20:10 on June 17, the measurement date and time of the measurement results of the sequence numbers 20 to 23 can be changed to 9:44:20 on June 18. , 10:10: 00, 10:26:40, 10:50:40. Further, by subtracting the count value 1440 of the reference data from the count value of the RTC at the time of measuring the measurement results of the sequence numbers 26 and 27, 1440 and 2880 are obtained as the difference time. Then, by adding these difference times to the measurement date and time of the reference data, which is 10:48:00 on July 3, the measurement date and time of the measurement results of the sequence numbers 26 and 27 will be 11:12: 00, 11 on July 3. : Specified as 26:00.

If No is determined in step S127, the control unit 240 subtracts the RTC count value at the time of measuring the measurement result acquired in step S118 from the RTC count value at the time of measuring the reference data as the difference time. The value is set (step S131). Then, the control unit 240 acquires the measurement date and time of the reference data (step S132), and subtracts the difference time set in step S131 from the measurement date and time acquired in step S132 as the measurement date and time of the measurement result acquired in step S118. The value is set (step S133). Then, the process proceeds to step S122. In the example of FIG. 29B, the RTC count value 1440 of the reference data is larger than the RTC count value 60 at the time of measuring the measurement result of the sequence number 24. Therefore, 1380 is obtained as the difference time by subtracting the RTC count value 60 at the time of measuring the measurement result of the sequence number 24 from the RTC count value 1440 at the time of measuring the reference data. Then, by subtracting this difference time from the measurement date and time of the reference data, which is 10:48:00 on July 3, the measurement date and time of the measurement result of the sequence number 24 is specified as 10:24:00 on July 3. ..
In addition, as a process after the reference data is acquired in step S126, even if the RTC count value at the time of measuring the reference data is larger than the RTC count value at the time of measuring the measurement result acquired in step S118, the difference time is used. , The value obtained by subtracting the RTC count value at the time of measuring the reference data from the RTC count value at the time of measuring the measurement result acquired in step S118 (that is, a negative value) is set, and the measurement result acquired at step S118 is measured. As the date and time, a value obtained by adding the difference time to the measurement date and time of the reference data may be set (that is, a date and time earlier than the measurement date and time of the reference data may be set). By doing so, the processing of steps S131 to S133 is equivalent to that of steps S128 to S130, so that the determination in step S127 can be omitted.

As described above, according to the present embodiment, regardless of the number of measurement results that are not transmitted from the sphygmomanometer 10 to the smartphone 20, or are transmitted from the sphygmomanometer 10 to the smartphone 20 but not received by the smartphone 20. If the measurement result recording unit 260 of the smartphone 20 has the same battery replacement count information and at least one measurement result for which a valid measurement date and time is specified is recorded, the measurement date and time can be specified. .. Further, since the difference processing of the RTC count value is not performed by the sphygmomanometer 10, the processing load of the sphygmomanometer 10 is small.

FIG. 30A is a diagram showing another example of the data structure of the measurement result recording unit 180 in the sphygmomanometer 10 according to the present embodiment. FIG. 30B is a diagram showing a specific example of the measurement date / time specifying process in the smartphone 20 according to the present embodiment and another example of a part of the data structure.
In this example, in the sphygmomanometer 10, since the measurement result recording unit 180 measured the blood pressure information 35 times more than 30 cases that can be recorded, the data of the measurement result recording unit 180 was overwritten and the sequence number 5 or less. The measurement result is not recorded. Further, the measurement results of sequence numbers 6 to 35 shown in FIG. 30A are cases where the measurement results are not transmitted to the smartphone 20 or are transmitted from the sphygmomanometer 10 but not received by the smartphone 20. However, the smartphone 20 has received the measurement result of the sequence number 5, and the battery replacement number information is 0 in this measurement result, and a valid measurement date and time, June 17, 19:50:00 is specified.

Regarding the measurement result of sequence number 6 in the example shown in FIG. 30A, when the measurement result in which the battery replacement number information is 0 is searched from the measurement result recording unit 260 in step S123, the measurement result of sequence number 5 is found, so that step S124 Is judged to be Yes. Then, using the measurement result of sequence number 5 as reference data, and using the RTC count value 4721037 at the time of measurement, the measurement date and time of the measurement result of sequence number 6 is June 17, 20: according to the processing of steps S128 to 130. It is specified as 10:00. Similarly, the measurement date and time are specified for the measurement results of sequence numbers 29 to 31 (the same applies to the measurement results of sequence numbers 7 to 28 omitted in the drawing). For the measurement results of sequence numbers 32 to 35, the measurement date and time are specified according to the processes of steps S119 to S121. The measurement date and time for the measurement results of sequence numbers 32 to 35 are specified according to steps S120 to 122, but detailed description thereof will be omitted.

In this way, even if the measurement result recorded in the measurement result recording unit 180 is overwritten without transmitting the measurement result in the sphygmomanometer 10, the same battery replacement frequency information is obtained and effective. If the smartphone 20 has a measurement result in which the measurement date and time is specified, the measurement date and time can be specified.

In the present embodiment, the sphygmomanometer 10 does not calculate the difference between the RTC count value at the time of measuring the blood pressure information and the RTC count value at the time of transmission. However, for the measurement result in which the battery replacement count information at the time of measuring the blood pressure information matches the latest battery replacement count information at the time of transmission, the blood pressure monitor 10 calculates the difference in the RTC count value, and the calculated difference is used. It may be transmitted to the smartphone 20 together with the blood pressure information.

In the present embodiment, when the measurement result including the same battery replacement count information as the battery replacement count information included in the measurement result transmitted from the sphygmomanometer 10 is not stored in the measurement result recording unit 260, the measurement date and time is set. It cannot be specified, and the measurement date and time is set to "invalid". Regarding the measurement result in which the measurement date and time is set to "invalid", as described in the exceptional case 2 of the first embodiment, the measurement result in which the measurement date and time is set to "invalid" is shown in FIG. It can be used in such an embodiment. When using the battery replacement count information, the measurement date and time is not limited to the case where the measurement date and time is set to "invalid" for all the measurement results of one battery replacement count, and the measurement date and time is set for all the measurement results of a plurality of battery replacement counts. It may be set as "invalid". Hereinafter, the case where the measurement date and time is set to "invalid" will be described for all the measurement results of the battery replacement number of 2 times and all the measurement results of the battery replacement number of 3 times. The same applies when there are three or more battery replacements for which the measurement date and time are set to "invalid" for all measurement results.

FIG. 31 shows a display example of the time course of systolic blood pressure as blood pressure information.
Here, it is assumed that the measurement dates and times such as t _n and t _m are specified for the measurement results of the sequence number n or less with one battery replacement and the sequence number m or more with four battery replacements, respectively. On the other hand, regarding the measurement results of the sequence numbers j to j + 2 in which the number of battery replacements is two, the intervals T _j and T _{j + 1} of the measurement dates and times of the sequence numbers j to j + 1 and the sequence numbers j + 1 to j + 2 are specified by the RTC count value. is made of. Similarly, for the measurement results of the sequence numbers _{k to k} + 1 in which the number of battery replacements is three, the interval T _{k of the} measurement date and time can be specified by the count value of the RTC. Therefore, the time interval of the data corresponding to these sequence numbers is set corresponding to the interval of the count value of each RTC. Then, when a temporary graph of the measurement result in which the measurement date and time is set to be "invalid" is placed in the graph showing the time-series change of the measurement result, the measurement in which the measurement date and time is set to "invalid" is performed. The period between the valid measurement date and time before and after the result is divided into a predetermined ratio with respect to the number of battery replacements of the measurement result whose measurement date and time is "invalid". Then, the measurement date and time is "invalid" so that the median t _c1 and t _{c2 in} the time direction of the measurement result in which the measurement date and time are set to be "invalid" match the median value of each of the plurality of divided time intervals. A temporary graph of the measurement result set as "" can be placed. In FIG. 31, the ratio between t _m and t _n , which are valid measurement dates and times before and after the measurement result in which the measurement date and time is set to “invalid”, is set according to the score of the measurement result of each battery replacement number. It is divided. That is, battery replacement number two measurements three points, because the battery replacement number three measurements result is two _points, t m -t _n 3: when divided into 2 _(t m _-t n) * The area where the provisional graph of the measurement result of each battery replacement number is arranged is divided by 3/5. The central _{t c1} graph of the temporary sequence number J～j + 2 measurement _{results, t c1 = {(t m} -t n) * 3/5-t n} is located in / 2, the sequence number k to k + 1 The center t _c2 of the provisional graph of the measurement result of is arranged at t _c2 = {t _m − (t _m −t _n ) * 3/5} / 2.

In this way, even for measurement results for which the exact measurement date and time cannot be specified, it is possible to know the relative time-series changes with other measurement results for which the measurement date and time can be specified, which is useful information for health management. Can be provided.

The method of arranging the provisional graph of the measurement result whose measurement date and time is set to "invalid" in the graph showing the time-series change of the measurement result is not limited to the above. For example, between t _m and t _n , which are valid measurement dates and times before and after the measurement result in which the measurement result is invalid, is divided into a ratio according to the score of the measurement result of each battery replacement number. , _Tm −t _n may be divided according to the width in the time direction of the RTC count value of the measurement result of each battery replacement number. In the example shown in FIG. 31, the width in the time direction of the RTC count value of the measurement result of the battery replacement number of two times is T _j + T _{j + 1} , and the time direction of the RTC count value of the measurement result of the battery replacement number of three times. The width of is T _k . Therefore, at the time when t _m −t _n is divided by the ratio of (T _j + T _{j + 1} ): T _k , it is divided into a plurality of time intervals in which a provisional graph of the measurement result of each battery replacement number is arranged. Then, the measurement date and time so that the _medians t _c1 and t _{c2 in} the time direction of the measurement result in which the measurement date and time are "invalid" match the median values of the plurality of time intervals divided in this way. You can place a tentative graph of the measurement results for which is set to "invalid".
